Hey guys, its actually the Oskar. It has a Neuspotter head with a hovercraft body.
Its not as well known because there is currently no styrene kit available.
Just doing a mock-up using blu-tack tonight and finding bits for my spares box...The original rocket launcher seems to be scratch-build from a pen cap. Here I used the cap of the hobby knife which has a similar shape.
The Oskar variant on the back is what I want to make...
